Uesugi

The Uesugi were a Japanese feudal clan that were based in Echigo Province in northern Central Honshu, as well as the Kanto Region. The Uesugi were known for their warrior monks, loyal to Buddhism, and their famed leader Kenshin Uesugi was among their number. They suffered in the Sengoku Jidai of 1545-1615, losing a string of battles against Shingen Takeda of the Takeda such as at the Fourth Battle of Kawanakajima, Battle of Tonegawa, and others, and were crushed at the Battle of Tetorigawa in 1577.
